LOADING APPARATUS.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed January 15, 1914. Serial No. 812,207.

To all whom it may concern:

Be it known that I, ALEXANDER V. JEN- BEN, a citizen of the DanishMonarchy, and a resident of Devils Slide,'Morgan county,

Utah, have invented certain new and use ful Improvements in LoadingApparatus, of which the following is a specification.

This invention relates to loading apparatoe with particular reference toan apparatus for loading bags of cement on board railroad cars. It willbe seen, however, as this specification proceeds in setting forth thedetailed construction of my invention, that it is not at all limited tothe loading of bags of cement, or in fact to loading of any particularpackage or kind of material, but that the features of my invention areadapted for use in loading diflerent kinds of material undercircumstances and conditions entirely different from thosespecificallydescribed or illustrated, and I wish it distinctly understood that I donot intend to limit the features or use of my invention except asdefined by the claims.

The object of my invention is to provide a loading apparatus for loadingpackages of materials, such as bags or cement or the like, on boardrailroad cars'in such a manner that the operation becomes safe and whereby the loading may be done f xpeditiously and two or more cars may beoaded at the same time.

Another object of my invention is to provide an apparatus of simplepractical construction adapted to be set up for use quickly andsecurely.

Still another object is to provide an apparatus which under certainconditions-may be used for unloading as well as for loading.

Other objects of the invention will appear as the specification proceedswhile reference is had to the accompanying drawing in which Figure 1 isa general view of an apparatus embodying my invention and showing thesame set up for loading two railroad cars,-and Fig. 2 is a detail viewof a ratchet mechanism.

The reference numeral 1 represents a building of a cement plant providedwith e conveyer 2 for conveying the bags of cement from the packingmachines, not shown.

3 and 4 represent railroad cars standing on parallel tracks. Heretoforeit has been proposed to load the two cars by using a long chute whichreached from the conveyor 2 through the car 3 into the car 4. Thisarrangement requires that the inner end of the chute be elevatedsufficiently to cause the bags of cement to slide down easily into thesecondcar, and this arrangement also necessitates that the packingmachines be elevated sufilciently to permit the conveyer 2, which islocated below said machines, to deliver th bags to the elevated end of.the chute afa ahi. When. for some reason one of the ca starts, Z Wrecksthe chute causmg serious damage and accidents. in the present inst ice Iarrange the loading a paratus an: a of... 1MP)? that even she (I one orboth ca mart no accident due to the wrecking of the conveyer will occur.i More.- over, the apparatus is JO arranged that the conveyer 2 may bequite low and the packing'niachincs need not be unduly elevated.

The conveyor 2' discharges onto an apron or chute 5, the bags passingover an idler 6 driven from the co ieyer by sprocket wheels and chainsindicated at 7. From 5 the bags slide down to a receiving apron or chute8 which is secured in the car opening by the following means; The apron8 is carried by a post 9 which is set up ertically in the door of thecar and which carries an upper and lower shoe-l0 and 1.1.. The post issecurely fixed in position so that the said feet will engage the floorand to= of the door opening by means of a. nut i the threaded stem 13 ofthe post. .y turning the nut the post will be lengtln ened and expandedso to speak in the door opening. The precise details of the door apronand accompanying parts are made the subject of a separate applicationfor patent filed. simultaneously with this application. A. secondreceiving door apron and fastening means for the same is secured in thedoor opening of the second car 4 as shown and the parts are nmnhered tocorr-- spend with those above.

1% denotes a truck provided with wheels 2 which and adapted to bewheeled into the car 3 through the door thereof. The said truck carriesa conveyer 16 in the form of a belt which runs over the drums 17 and 18.The conveyer 16 discharges into a discharging apron 19 over an idler 20driven from the drum 18 by sprocket wheels and chains at 21. If desired,the apron 19 may be hinged to the drum shaft so as to be collapsible.The apron 19 discharges into the second door apron 8, which dischargesinto the car 4. The conveyer\16 may be adjusted trans- I versely of thecar and secured in position by means of two clamps 22, 22 at the ends ofchains 23, 23 adapted to be wound around shafts 24, 24 by a ratchetwheel 25 and pawl 26 as shown in Fig. 2, in which 27 is a sto dog forthe ratchet wheel to prevent-accidental rotation thereof as is usual.The truck conveyer 16 is rovided with guide rails 28 to guard the agsagainst falling off of the conveyer. It should be noted, however, thatthe guide rails do not extend clear to the apron 8 at the lower end ofthe conveyer, but that at 29 bags may be removed for loading car 3. Forinstance, every other bag may be taken ed at 29 for car 3 and everyother bag pass into car 4 to be stacked by hand in each car. i

In operation the two railroad cars are placed on the tracks with theirdoors in alinement with the door of the building 1. The door aprons 8are placed in position and the truck conveyer wheeled into car 3 andadjusted transversely and secured by the clamps 11, and the chain 30 isplaced on sprocket wheels 31 and 3; for driving con veyer 16. It willthen be understood that the bags of cement are carried by conveyer 2 toaprons 5 and S, and by conveyer 16 to aprons 5 and 8 into our 4, and asnoted, bags may be taken off at 29 to load car 3. The aprons 8 areprovided with lips 39 which reach under aprons 5 and 19.

It will be observed that the entire arrange ment is very simple andquickly set up and taken down. Again, in case either of the ca rs shouldcommence to move, no harm will be done to the apparatus. If the car 3moves, it will take with it the truck conveyer 1G and the apron 8secured to the car. The chain 30 is the only physical connection betweenthe truck conveyor and the conveyer When the car 3 moves accidentally,the chain 30 may break or either of the sprocket wheels 31 and 32 may bearranged to slide off its shaft to prevent injury. \Vhen car 1 movesaccidentally, it takes its apron 8 along but causes he breaks of anykind.

As already pointed out, this loading apparatus may be used for unloadingalso in that the ronvever 16 may discharge at its elevated end on to aconveyer 2.

As here described and illustrated the in vention comprises a portableconveyer 16 adapted to be placed in a railroad car and fixed door apronsfrom which and into railroad car from another railroad car comprising incombination a receiving apron, means for securing the same in the dooropening of the car to be loaded, a discharging apron supported in theother car and arranged to discharge into the said receiving apron, thesaid two aprons being adapted to be adjusted laterally with respect toeach other and coiiveying means in said other car for conveying materialto the said discharging apron.
